A combination of thin film colorimetric interferometry and phase shifting interferometry has been used to study the behaviour of real and artificially produced roughness features within lubricated contact. The phase shifting interferometry was used to measure in-situ initial undeformed rough surface profiles and thin film colorimetric interferometry provided accurate information about micro-EHD film thickness behaviour over a wide range of operating conditions. Lubricant film thickness distribution within mixed EHD contact has been found to change significantly as a function of a slide-roll ratio. A high resolution color camera was used to provide a closer look at film thickness changes in the vicinity of surface irregularities.

Kolorimetrická interferometri byla použita ke studiu mazaných kontaktů pracujících za podmínek smíšeného mazání. Byl pozorován vliv provozních podmínek na změny v mazacím filmu. Rozložení tloušťky mazacího filmu bylo srovnáno s původní topografií třecího povrchu.
